Abstract:
A method of operating a programmable charge pump includes configuring each of a plurality of cascaded charge pump stages to be in a first set of charge pump stages or in a second set of charge pump stages based on an indicator of a target output voltage level. The first set of charge pump stages is configured to level-shift a first voltage level to a second voltage level. Each charge pump stage of the second set of charge pump stages has a disabled pump circuit portion. The second set of charge pump stages is configured to pass a version of the second voltage level to an output node of the programmable charge pump.
